An independent peptide reference — no sellers, every claim sourced

Trusted sources & further reading

The point of this site is that you do not have to take its word for anything. These are the public, authoritative places the entries are built from and checked against — the same tools you can use to verify a claim, or go further than any entry does.

Every link below is a primary, non-commercial source: a research index, a regulator, an anti-doping body or a public-health organisation. None of them sells anything. If a claim on this site matters to you, one of these is where to check it.

The research itself

PubMed
The index of the biomedical literature. Almost every citation on this site resolves to a PubMed record; abstracts are free, and many link the full paper.
PMC (PubMed Central)
Free full text for a large share of that literature — the paper itself, not just the abstract.
ClinicalTrials.gov
The registry of clinical trials. Useful for seeing whether a compound has actually been tested in humans, at what stage, and whether a programme was completed or quietly stopped.
Cochrane Library
Systematic reviews — the strongest single thing to read on a question, when a recent one exists.

Drug labels & approvals

DailyMed
The official, current FDA drug labels. Where the doses and warnings for approved medicines are read from, rather than repeated second-hand.
Drugs@FDA
Whether, and for what, the FDA has approved a drug in the United States, with the approval documents behind it.
EMA — medicines
The European Medicines Agency's assessments and product information for medicines authorised (or refused) in the EU.
MHRA
The UK medicines regulator — its approvals, safety alerts and guidance.

Sport & anti-doping

WADA Prohibited List
The World Anti-Doping Agency's list of substances banned in sport, reissued each January. The definitive text behind every doping-status line here.
Global DRO
Checks a specific product, in a specific country and sport, against the anti-doping rules — which the list itself cannot do.

Safety & harm reduction

FDA — for consumers
Safety communications and warnings, including the alerts on compounded and grey-market products this site cites.
CDC — injection safety
The public-health guidance behind the injection-safety page: one needle, one syringe, one time.
NHS
Plain, reliable patient information on conditions and their warning signs — useful for the infections and side effects the entries mention.
National Harm Reduction Coalition
Practical harm-reduction guidance for people who inject, written to reduce risk rather than to moralise.
